Product Description
Simpson MSTA12Z MSTA 12-in. 18-Gauge ZMAX Galvanized Medium Strap Tie is a Simpson Strong-Tie engineered connector designed to resist tension loads in wood-to-wood uplift applications. This 12-inch medium strap tie features a staggered nail pattern to help minimize wood splitting and is specifically designed for use on the edge of 2x members, making it a reliable choice for floor-to-floor clear span connections. The ZMAX galvanized coating delivers superior corrosion resistance, making this strap tie well suited for exterior and treated-wood environments.

Frequently Asked Questions
- What type of fasteners should be used to install the MSTA12Z?
- The MSTA12Z should be installed with 10d common nails or #9 x 1-1/2 in. Strong-Drive SD screws for proper load-rated performance.
- Why is the ZMAX coating important for the MSTA12Z?
- ZMAX galvanization offers extra corrosion resistance, making the MSTA12Z suitable for exterior and treated-wood applications where standard galvanized coatings may not provide adequate protection.
- How does the staggered nail pattern on the MSTA12Z benefit the installation?
- The staggered nail pattern is specifically designed to help minimize wood splitting during installation, which helps maintain the structural integrity of the connected members.
- What distinguishes a load-rated strap tie from a field-fabricated strap?
- Unlike field-fabricated straps, the MSTA12Z is load rated with the correct thickness and number of fasteners, ensuring predictable and code-compliant performance for resisting tension loads in wood-to-wood uplift applications.
